【摘要】 通过使良性蠕虫传播有序化、分级化,在扩散过程中减少了其对网络的冲击,提高了传播速 度,提出了基于地址的预制式网络划分算法,能够预先设定良性蠕虫的传播轨迹,预先测评良性蠕虫 的并行度,增强了良性蠕虫的可追踪性、可控性,给出了良性蠕虫采用这种算法传播的数学模型和模 拟实验．制定了蠕虫对网络流量冲击影响的通用标准．最后模拟一种类似Sapphire的蠕虫,令其采用 蠕虫常用的扫描策略进行传播,模拟结果表明,和传统传播策略相比,在预制式网络划分的基础上采 用分级式传播的良性蠕虫扩散速度快,产生流量影响小．更多还原

【Abstract】 This paper proposes a new propagation model, in which the friendly worms propagate in an ordered and hierarchy way, to reduce the impact to network and promote the speed during the friendly worm propagation. An addressed-based scheduled partition policy (ASPP) is also proposed, which can compute the friendly worm propagation track, enhance the parallel degree, and make the friendly worm more controllable after being sent out. The corresponding mathematical propagation model and a normal criterion for evaluating the traffic impact to network are proposed. As a case study, this paper simulates a worm like Sapphire, and the results showed that the friendly worms propagating in ASPP model are faster and bring less traffic load to network than traditional model.更多还原
